Run gofumpt on all files (#10392)
* Run gofumpt on all files

Getting golangci-lint errors when building on my laptop, possibly because I have newer version of gofumpt then what it was formatted with.
Run gofumpt -w -extra on all files as it will be needed in the future anyway.

* Update golangci-lint to v1.44.2

v1.44.0 upgraded gofumpt so bumping version in CI will help keep formatting correct for everyone

* Address golangci-lint error

Getting 'error-strings: error strings should not be capitalized or end with punctuation or a newline' from revive here.
Drop new line.

beorn7 b39f2739e5 PromQL: Always enable negative offset and @ modifier
This follows the line of argument that the invariant of not looking
ahead of the query time was merely emerging behavior and not a
documented stable feature. Any query that looks ahead of the query
time was simply invalid before the introduction of the negative offset
and the @ modifier.

Initial draft of prometheus-agent (#8785)
* Initial draft of prometheus-agent

This commit introduces a new binary, prometheus-agent, based on the
Grafana Agent code. It runs a WAL-only version of prometheus without the
TSDB, alerting, or rule evaluations. It is intended to be used to
remote_write to Prometheus or another remote_write receiver.

By default, prometheus-agent will listen on port 9095 to not collide
with the prometheus default of 9090.

Truncation of the WAL cooperates on a best-effort case with Remote
Write. Every time the WAL is truncated, the minimum timestamp of data to
truncate is determined by the lowest sent timestamp of all samples
across all remote_write endpoints. This gives loose guarantees that data
from the WAL will not try to be removed until the maximum sample
lifetime passes or remote_write starts functionining.

* Implement LabelNamesFor

This method provides the label names that appear in the postings
provided. We do that deeper than the label values because we know
beforehand that most of the label names we'll be the same across
different postings, and we don't want to go down an up looking up the
same symbols for all different series.

Tom Wilkie d479151f1f Various enhancements and refactorings for remote write receiver:
- Remove unrelated changes
- Refactor code out of the API module - that is already getting pretty crowded.
- Don't track reference for AddFast in remote write.  This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series.  For now, its easier and safer to always use the 'slow' path.
- Return 400 on out of order samples.
- Use remote.DecodeWriteRequest in the remote write adapters.
- Put this behing the 'remote-write-server' feature flag
- Add some (very) basic docs.
- Used named return & add test for commit error propagation

tsdb: Added ChunkQueryable implementations to db; unified MergeSeriesSets and vertical to single struct. (#7069)
* tsdb: Added ChunkQueryable implementations to db; unified compactor, querier and fanout block iterating.

Chained to https://github.com/prometheus/prometheus/pull/7059

* NewMerge(Chunk)Querier now takies multiple primaries allowing tsdb DB code to use it.
* Added single SeriesEntry / ChunkEntry for all series implementations.
* Unified all vertical, and non vertical for compact and querying to single
merge series / chunk sets by reusing VerticalSeriesMergeFunc for overlapping algorithm (same logic as before)
* Added block (Base/Chunk/)Querier for block querying. We then use populateAndTomb(Base/Chunk/) to iterate over chunks or samples.
* Refactored endpoint tests and querier tests to include subtests.

storage: Adjusted fully storage layer support for chunk iterators: Remote read client, readyStorage, fanout. (#7059)
* Fixed nits introduced by https://github.com/prometheus/prometheus/pull/7334
* Added ChunkQueryable implementation to fanout and readyStorage.
* Added more comments.
* Changed NewVerticalChunkSeriesMerger to CompactingChunkSeriesMerger, removed tiny interface by reusing VerticalSeriesMergeFunc for overlapping algorithm for
both chunks and series, for both querying and compacting (!) + made sure duplicates are merged.
* Added ErrChunkSeriesSet
* Added Samples interface for seamless []promb.Sample to []tsdbutil.Sample conversion.
* Deprecating non chunks serieset based StreamChunkedReadResponses, added chunk one.
* Improved tests.
* Split remote client into Write (old storage) and read.
* Queryable client is now SampleAndChunkQueryable. Since we cannot use nice QueryableFunc I moved
all config based options to sampleAndChunkQueryableClient to aboid boilerplate.

In next commit: Changes for TSDB.
